Abstract

The invention belongs to the technical field of power electronics and relates to an intelligent identification power supply during power grid blackout or artificial-switching power-off. The intelligent identification power supply comprises a low-power-consumption single-chip microcomputer, a positive-voltage reference voltage source chip and a periphery auxiliary circuit, wherein the single-chip microcomputer determines whether a circuit is powered down by detecting the output voltage of a single-phase rectifying module; the positive-voltage reference voltage source chip provides a stable supply voltage for the single-chip microcomputer; and the periphery auxiliary circuit provides a signal amplifying and transferring function for the single-chip microcomputer. The intelligent identification power supply can be applied to the technical field of engineering such as common light-emitting diodes being upgraded to intelligent lamps with an emergency lighting function, the intelligent control of uninterruptible power supplies, giving an alarm during power failure and the like.

Description

Technical field [0001] The present invention belongs to the field of power electronics technology, and relates to a new type of intelligent power supply for power grid blackout or artificial switch-off. The invention can be applied to upgrade ordinary light-emitting diode lamps to intelligent lamps with emergency lighting functions, intelligent control of uninterrupted power supplies, Power failure alarm and other engineering technical fields. Background technique [0002] The existing power outage emergency products can only work in two modes: power-off action and power-off delay action, and additional lines need to be arranged in the electrical circuit to supply power. If the existing power failure emergency products are directly installed on the existing general lighting circuit, the power supply control of the power failure emergency products cannot be performed through the switches connected in series on the existing lines. Therefore, the present invention proposes a new ty...
